Illuminating apparatus for liquid crystal display device



The article according to the design is incorporated in a portabletelephone, a portable terminal for information device, etc. so as toilluminate a liquid crystal display from the front side.

Light emitted from the light source, traveling through a lightconductive member and a light diffusing plate and introduced into alight conductive plate uniformly illuminates the whole surface of theliquid crystal display thanks to micro-prisms formed on the surface ofthe light conductive plate.

A transparent cover is provided over the exposed surface of the articleincorporated in the portable telephone, etc. so as to protect themicro-prisms from dust, dirt, scratches, etc.

FIG. 1 is a front view of an illuminating apparatus for liquid crystaldisplay device showing our new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a bottom view thereof;

FIG. 4 is a left side view thereof;

FIG. 5 is a right side view thereof;

FIG. 6 is a rear thereof;

FIG. 7 is a cross-sectional view taken along the line 7—7 of FIG. 1;

FIG. 8 is a cross-sectional view taken along the line 8—8 of FIG. 1;and,

FIG. 9 is an enlarged view of the portions 9 and 9 of FIG. 7.

A light source (i.e., light emitting diode) for illumination is disposedinside a housing frame which is shown at the lower side of FIG. 1.

Two flexible printed circuit boards extending downwardly in FIG. 1 areconnected to a power source.

The ornamental design for an illuminating apparatus for liquid crystaldisplay device, as shown and described.
